This is a MP3 Music Player that works on the Incognito. It may also work on other iDEN and CDMA Boost phones that have memory card. It installs and runs on the Motorola Rambler but doesn’t work because the phone doesn’t support a memory card and 3rd party apps aren’t allowed to access internal file system of any Boost phone.

According to BoostApps Forum member imagine126 who found it on GetJar, LPlayer, unlike the built in Incognito music player, has a shuffle mode and can play in the background.

One quirk of LPlayer is that all music files have to be in a single folder or it will not work at all.
